The 30-year-old "Dark Horse" hitmaker feels studying history would benefit her future, reported Female First.
"If I could go back to school, I would study history. I'd study world history, just to know how people work, and how they evolved, and where we come from. I feel like when you know about what happened in the past you can do better for your future," she said.
The pop rock sensation has previously revealed that she wanted to become an art collector after being inspired by Beverly Hills gallerist Marc Selwyn.
